WALTER R. KAHNS, OF BROOKLYN, NEW YORK, ASSIGNOR TO I. H. WHITE MANUFAC- TURING COMPANY, OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK.

ELECTRIC-CANDLE LIGHTING FIXTURE.

Application filed May 21, 1921.

To all whom it may concern Be it known that I, VALTER R. KAHNs, a citizen of the United States, residing at the borough oi Brooklyn, in the county 01 Kings, city and State of New.York, have invented an Improvement in Electric-Candle Lighting Fixtures, of which the following is a specification.

My invention relates to lighting fixtures of the electric candle type, in which a socket for the lamp is supported within a vertical tube which has heretofore commonly been made of metal, rendering it necessary to employ a cover of insulating material around the socket shell to insulate it irom the metal candle tube.

These tubes have heretofore been supported at the bottom within. a cup provided with a shoulder or flange upon which the bottom of the candle tube is seated.

In fixtures of this character, various lengths of candle tubes are employed, rendering it necessary to employ supports of diilerent lengths according to the lengths of the tubes, so that the lamp sockets may be properly positioned therein.

One object of my present invention is to avoid the necessity of employing the usual insulating cover for the socket shell; an other object is to provide for the hanging of the candle tube at its upper part upon the socket; and a further object is to provide means for strengthening the socket support and guiding the movable sliding members in a uniform and secure manner.

The details of the invention are hereinafter particularly described.

In the accompanying drawing- Figure 1, is a sectional elevation of a candle fixture illustrating my invention applied thereto.

Fig. 2, is a sectional side elevation showing a modification.

Fig. 3, is a perspective view of the socket support detached.

Fig. l, is a section of such support taken on the broken lines 4.4 of Fig. 1. I

Fig. 5. is an inverted plan view of the socket detached with one of the supporting members secured thereto partly in section, and

Fig. 6, is a fragmental vertical section of the sliding members.

Specification of Letters Patent.

Serial no. 471,302.

Similar reference characters denote like parts throughout the several figures.

Referring to the drawing, 10 indicates a candle tube of hard fiber or other non-conducting material the upper portion of which is preferably thickened for a predetermined distance, so that the diameter of the upper portion of the tube is of a size adapted to fit over and around the shell. 11 of a lamp socket 16 providing an annular shoulder 12, on the interior or the tube. This thicker portion of the tube takes the place of the common cover of insulating material heretoiore employed around the socket shell, the shoulder 12, being seated upon the annular flange 17, provided upon the porcelain bot tom of the socket 16.

If desired however, the thickened portion of the tube may be of less extent than shown in Fig. 1, or an annular rib 19, may be formed on the interior of the tube at the proper distance from its top to rest upon the flange 17 of the socket, as illustrated in Fig. 2.

21 and 22 indicate two vertical members slidably connected together, and each formed from a flat strip of metal.

The longitudinal edges of the member 21 are bent outwardly at right angles leaving a space between them very slightly wider than the width of the member 22. These ri ht angle edges are then again bent at right angles towards each other leaving a space between them and the flat portion of the member 21, slightly greater than the thickness of the member 22, and also leaving a longitudinal space between the bent over edges.

The extreme edge of the flat portion of the member 21, is depressed at its center forming a slight projection 23, which comes within the space between the edges of the longitudinal bends. The upper end of the member 21, above the bent over edges, is provided with a recess 24}, and bent at right angles, forming two divergent arms 25 and 26, which are provided at their ends with screw holes for the passage of screws 27 by which this member is secured to the bottom of the socket 16.

The member 22 is of a width and thickness to fit slidably within and between the bent over portions of the member 21., and is provided with a central longitudinal rib 28 on one side, which may be formed by stamping it out of the strip leaving acorrssponding depression or groove 29 in the opposite side of the strip. I

The rib 28 fits into the longitudinal space between the overturned edges of the mem ber 21, so that this member 22 is vertically slidable therein being guided the full length of its movement by said overturned edges on the member 21 and the rib 28.

Adjacent the upper end of the member 22 there is provided a threaded hole which receives a set screw by means of which these members may be clamped together at any point to which they may be adjusted. The projection 23 on the member 21, when the two members are assembled takes into the longitudinal groove 29, in the member 22, thereby not only forming an additional guide, but also preventing the accidental separation of these members after they have been connected together, as said projection 23 will take against the end of the set screw 30 when the member 22 is drawn down near the lower end of the member 21, unless said screw has been intentionally withdrawn, or loosened sufficently t pass said projection.

The lower or free end of the member 22, is bent at right angles and has formed thereon aninteriorly threaded stud 81, which is screwed upon the threaded end 1.3, of a pipe or tube 14-, extending from a chandelier, wall bracket or other support.

A cup shaped shell 15, is preferably employed to cover the lower end of they candle tube, which shell is provided with a central opening in its bottom fitting over the threaded end of the pipe 1 1, and held in place by the stud 31, on the member 22, which is screwed down uponthe shell.

I I claim as my invention:

1. A support for a lamp socket in electric candle fixtures, comprising two members, each formed from a fiat strip of metal, one member being provided with a central ion gitudinal rib on one side. and a correspond ing groove in its opposite side with fiat latteral projections on each side thereof, the other member having its longitudinal edges folded over the fiat sides of the first member and extending to the rib on the other member leaving a longitudinal slot, into which said rib projects, said second member being provided at its top or free end with two divergent arms having screw holes therein for attachment to the bottom of the socket. said first member carrying at its lower end a stud for connection with a pipe terminal, and a set screw passing through a threaded opening in said rib on the first member.

2. A support for a lamp socket in electric candle fixtures, comprising two members each formed from a flat strip of metal,

one member being provided with a central longitudinal rib on one side and a corresponding groove in its opposite side with flat lateral projections on each side thereof, the other member being provided with an inturned projection on its lower edge entering the groove in the first member and having its longitudinal edges folded over the flat sides of the first member and extending to the rib on the other member leaving alongitudinal slot into which said rib projects, said second member being provided at its top with two divergent arms having s rew holes therein. for att chment to the bottom of the socket, said first member carrying at its lower end a stud for connection with a pipe terminal, and a set screw pass ing through a threaded opening in said rib on the first member.
